CIGAR-ROLLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 566,058, dated August 18, 1896.

Application filed January 8, 1896.

T0 aZZ whom it may concern.-

Be it known that I, JOHN BUNN, a citizen of the United States, residing at Binghamton, in the county of Broome and State of New York, have invented certain new and useful Improvements in Cigar-Rolling Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form part of this specification.

My invention relates to cigar-rolling machines designed to apply the wrapper to the cigar-bunch, and has for its object to increase the efiectiveness of machines of this class, whereby better results may be attained.

The principal features of my invention are a series of adjustable pressure rollers arranged end to end, which bear on the cigarbunch while it is being rolled, each roller being separately adjustable, whereby the pressure can be applied uniformly over the length of the bunch irrespective of its shape, and a pivoted table on which the wrapper is supported while being wound on the bunch.

- These and other features of my invention will be hereinafter fully described, and more particularly pointed out in the claims.

Referring to the drawings, Figure 1 represents a top view of my improved machine. Fig. 2 is a front view showing the rollers in a tilted position. Fig. 3 is a rear View showing the rollers in the same position as in Fig. 2. Fig. 4. is a vertical sectional View on the line a: a: of Fig. 1. Fig. 5 is a view of the stretcher detached from the machine. Fig. 6 is a sectional detail view of part of one of the posts and gearing. Fig. 7 is a view of the presser-rollers detached and showing a modification, and Fig. 8 is a sectional View of a detached detail. Fig. 9 is a sectional view of a portion of the wrapper-supporting table and a plate on which it is adjustably supported. Fig. 10 is a plan of a portion of the bed-plate of the machine, showing a 7 detail of construction. I Similar letters of reference indicate corre- Serial No- 574,711. (N0 model.)

sponding parts in each figure of the drawings.

A represents the bed-plate of the machine, from which the standard a, a, and a rise.

B is the main driving-shaft, journaled in the standards a and a, and provided with suitable driving-pulleys b. The shaft B carries a gear I), which is intermediate of and meshes with similar gears c and d on the ends of the shafts c and d, journaled in the standards a and a and which carry the rollers O and D, which rollers are therefore positively driven. The rollers O and D support and rotate the bunch while it is being wrapped.

E is a hollow standard enlarged at its lower end, and adjustably held in the elongated opening a in the bed-plate A by means of the clamping-nut e, as shown in Figs. 3, 8, and 10. The upper end of the standard is split and provided with the exterior clampingnut 6 F is a post adapted to fit in the hollow standard E, and is adj ustably held therein by the clamping'nut 6 as shown in Fig. 8. The post F is provided at its upper end with a plate f, having downwardlyextending ears f G is another plate provided with down wardly-extending ears 9, which are hinged to the ears f by means of the rod '9. A coiled spring 9 is arranged on the rod 9 and is so connected to the plates f and G as to normally force the plate G against the plate f, the latter being stationary and the former movable on the hinged joint. A lever 9 extends rearwardly from the plate G from, which a rod g extends to a foottreadle (not shown) beneath the bed-plate, which enables the operator to lift the plate G against the force of the spring 9 as will be referred to hereinafter.

The plate G is provided with suitable boxes h h, in which the rods hh are journaled. These rods are adapted to have rotary and longitudinal movement in the boxes h h, and are held in the desired position by set-screws 71 71 To the front ends of the rods h h are hinged the shanks h of the frames h, carrying the presser-rollers H H, the latter being arranged end to end. The rollers H can therefore have a swinging vertical adjustment relative to the rods 71. h, and be held in any desired position by the screws 715 ff, which form the pintles of the hinges.

As the standard E can be adjusted on the bed-plate A, it follows that the post F and all it carries are also adjustable relative to the bed-plate, and such adjustment results in adjusting the pressenrollers H longitudinally relative to the rollers O and D.

I is a set-screw working in the plate G and engaging the plate f, and by means of which the plate G and the presser-rollers H are vertically adjusted and the downward pressure of the said rollers on the tobacco bunch,

caused by the action of the spring g is restricted and regulated.

From the foregoing it will be seen that the presser-rollers H II have a spring-actuated pressure on the tobacco bunch when the latter is supported on the rollers C D, which pressure can be adjusted, and also that said rollers can be separately adjusted relatively to the rollers G D, so that they will lie in planes either parallel with the planes of the rollers O D or at any desired angle thereto, and also that they can be adjusted vertically, laterally, and longitudinally to the rollers O D, so that various sized and shaped bunches may be operated on in such manner that substantially uniform pressure is applied throughout the length of the bunch; also that by operating the foot-treadle connected with the rod g the presser-rollers II II can be elevated simultaneously to enable the operator to insert a bunch or remove a cigar from the supporting and rotating rollers O and D.

J is the stretcher attached to and supported by the standard a to have a slight vertical and lateral adjustment relative to the rollers O and D. This stretcher is a metal plate convex in cross-section and tapering slightly from the butt to the tip end, as shown in Fig. 5. It is provided with the ,usual tip-forming cavity j, into which paste is conveyed from the paste-cylinder K through the tube and orifice 7c. The pasting devices form no part of this present invention and will not therefore be particularly described. The stretcher is adjustably connected to the bracket J by means of the set-screw 7", which passes through a slot in the bracket, and the bracket is adjustably connected to the standard a by means of a set-screw 3' which passes through a slot in the standard a L is the wrapper-supportingtable, which is adj ustably connected to the plate m by means of the screw-boltm, attached to the table L, which passes through the slot m in the plate m and receives the clamping-nut m The plate m is provided at one corner with a post M, which is revolubly supported in suitable bearings n n, as seen in Figs. 2 and 3. In order to rotate the post M, I provide a sleeve O,fitting over the post M between the bearings 01 n. This sleeve is connected to the post by means of a pin 0, which passes through the sleeve and a slot 0 in the post, as seen in Fig. 6. By this arrangement the sleeve has a limited vertical movement relative to the post, but both have a uniform rotary movement. The sleeve is provided with upper and lower beveled gears 0 0 ,which, however, have teeth only on one-fourth of their circumference, in order to give the post and table only one fourth of a complete revolution.

The shaft (1 is provided with a pinion 19, meshing with the gear 19 on the shaft 11 supported in suitable bearings, and the shaft 13 carries a bevel-gear p with which the gears 0 0 are adapted to be brought into engagement at the will of the operator. Q is a lever provided at one end with a strap (1 to engage the sleeve 0. This lever is pivoted on a standard q, and a spring g attached to its other end and to the bed-plate A, normally tends to keep the gear 0 in engagement with the gear 19 and preferably this engagement between the gears o and 19 will turn the table one-quarter of a circle from the position it occupies in Fig. 1, in full lines to the left, as indicated by the dotted lines in said figure.

In order to bring the gear 0 into engagement with the gear 19 a rod (1 is connected to the lever Q in front of its pivot and to a treadle beneath the bed-plate, (not shown,) which enables the operator at his pleasure to depress the front end of the lever against the force of the spring g and so pull the sleeve 0 down and bring the gear 0 into engagement with the gear 13 This will cause the table to move from the position indicated in dotted lines in Fig. 1 to that shown in full lines. In order to give the table L vertical adjustment relative to the rollers O and D, a collar R is placed on the post M, which collar rests on the lower bearing a. A set-screw 1" passes through the collar R and engages the post M. By loosening the screw 4" the post can be elevated or lowered, as desired.

I have herein particularly described and illustrated only two adjustable presser-rollers, but it is evident that four or even more such rollers may be employed, as indicated in Fig. 7, as it would only require a duplication of the adjusting devices employed for the two rollers.

S is a finger for holding the tuck end of the wrapper at the beginning of the wrapping operation. This, however, is not an essential feature of my invention, and will not there fore be particularly described.

The advantage of the pivoted table is that it brings the wrapper into the necessary position to properly wind it spirally on the bunch without straining the wrapper, as is the case when the wrapper-table is moved lengthwise of the bunch.

The principal advantage of the adjustable presser-rollers is that it enables the operator tive of its shape.

to apply substantially uniform pressure throughout the length of the bunch irrespec- Where a single straight roller has heretofore been used the pressure on bunches tapering toward both ends was necessarily only on a limited portion of the bunch, and, owing to inadequate pressure, the bunch was often thrown out of the machine by the operation of the positively-driven rollers. By my improvements the cigar-bun ch is securely held in position with its tip end in the tip-forming cavity of the stretcher, and this is very important, as it is well known that the tip is the most difficult part to properly wrap.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is
